Choosing the Central Air System That is Right For You

Generally speaking, there are four forms of central air conditioning:

Split systems will be the most typical form of central air conditioner found in the U.S. Within your house, tucked in a cabinet, is the evaporator coil, which removes moisture and heat in the atmosphere. Outside your house, a metal case contains the condenser coil, which discharges the heat, and also the compressor, which pumps refrigerant between both coils.

The indoor part of the air conditioner is connected to a network of ducts, and also a blower circulates the chilly air through them to reach all elements of your house. This kind of system is the most efficient to set up with a central furnace in a house, since it may share the ductwork utilized by the heating system. Each of the central air conditioner systems in this report are split systems.

Heat pumps are a variation of the conventional split system. During hot summertime, it releases it outside and pumps heat from the house. In the wintertime, it pulls heat in the outdoor air and uses it to warm the house.

Heat pumps may be used efficiently for both cooling system and heating in mild climates as a result of that. Nevertheless, heat pumps don’t usually function very well so they’re really not the best option for cold climates, when temperatures remain below freezing for a long time. A specialized kind of heat pump, called a ground-source or geothermal heat pump, could be an alternative for colder environments. By drawing heat out of the ground instead of the air, it works.

Packaged central air conditioners combine compressor, condenser and the evaporator in one unit. The air conditioner is ordinarily put on a roof or a concrete slab near the base. Ducts running through the exterior wall or roof draw air from in your house and return cooled air indoors. This sort of air conditioner may also be utilized in small commercial buildings. When combined with a couple of heating coils or a natural gas furnace, it removes the need for a separate furnace within the building.

Ductless mini-split systems could be the ideal choice for houses that don’t have ductwork. Like a split system that is fundamental, the ductless mini-split combines an outdoor compressor and condenser with one or maybe more indoor air-handling units. These units have blowers attached and are mounted high. Tubing connects the outdoor and indoor units and circulates refrigerant between them. Each indoor unit is installed in a different room and cools that room only, much just like a window air conditioner.

The main benefit of ductless mini-split systems is that they can be set up without tearing up walls to set up ductwork. In addition they allow the stream of cold air to be controlled independently in each room (or shut off altogether in empty rooms). If used to cool an entire house, mini-split systems are somewhat more expensive than ducted central air conditioning systems, costing roughly 30 percent more for exactly the same amount of cooling power. Yet, they are also more effective, since they prevent the power loss associated with ductwork.
